Question

Avem progresia geometrica :b1=6 q=1/2 determinati b2,b3,b4,b5

Answer 1

Răspuns:

Explicație pas cu pas:

b1=6 q=1/2

b2=b1*q=16*1/2=8

b3=b2*q=8*1/2=4

b4=b3*q=4*1/2=2

b5=b4*q=2*1/2=1

Answer 2

Răspuns:

3 ; 3/2 ; 3/4 ; 3/8

Explicație pas cu pas:

b₁ = 6 ; q = 1/2

--------------------

b₂ = b₁·q = 6·1/2 = 6/2 = 3

b₃ = b₂·q = 3·1/2 = 3/2

b₄ = b₃·q = 3/2 ·1/2 = 3/4

b₅ = b₄·q = 3/4·1/2 = 3/8
